The lens diameter is alternatively 3 mm or 5 mm. The signal lamps are equipped with low current LEDs in white or RGB and have a wire connection or a plug connector for 2×2 sockets (RM 2.54 mm). Special customised versions can easily be created thanks to the modular basic concept of the signal lamps. This means that the SMD-LED can be changed: single-colour, special colours or duo LED, IR or night vision are all possible. The signal lamps can be equipped with I²C controllers, series resistors or an alternative electrical connection. As a rule, these customised versions do not incur additional tool costs. Furthermore, coloured lenses or special lens shapes are possible, as are alternative housing colours or different cover shapes and sizes.
You can find detailed information on the standard items in our range of signal lamps for IP68 applications here and also in our e-catalogue. You can download the technical data sheet for these items from our e-catalogue or here.
Please note that the standard lighting solutions presented here will meet the requirements of protection class IP68 only if the device meets certain requirements. Our light guides and signal lamps require a certain minimum thickness on the housing front in which they are mounted and they must not fall short of this requirement. This is 1.0 mm when using rigid and flexible light guides, and 1.5 mm for the signal lamps presented. To ensure assembly is IP68-compliant, the assembly holes in the housing must take due account of ISO tolerance class H7. The rigid and flexible light guides are intended for use in ambient temperatures between -20°C and +50°C. With the signal lamps in the 2660 series, the range of possible ambient temperatures lies between -20 and +80°C.
